A process for partial conversion and low-temp transform of CO in the synthetic ammonia plant where coal is used to generate gas features that the Fe-Mo catalyst for partial conversion of CO, anti-poisoning agent and Co-Mo catalyst for low-temp conversion are used and the temp of semi-water gas is controlled to 200-260 deg.C at entering anti-poisoning layer, and 150-250 deg.C at the segments of said Co-Mo catalyst layer, and lower than 300 deg.C at bed layer to prevent high-temp reversal of sulfurizing reaction and make the catalyst activity optimal. Its advantages are long service life of catalyst, low system resistance, saving energy and convenient operation.

本发明是中小合成氨厂以一种CO部分转化抗毒保护层配低温变换的工艺，涉及煤造气合成氨厂0.6～2.0MPa半水煤气变换工艺流程，该工艺用铁－钼CO部分转化催化剂、抗毒剂，配钴－钼低变催化剂，半水煤气进入部分转化抗毒层温度为200～260℃，进钴－钼低变催化剂各段温度为150～250℃，床层温度控制在300℃以内，避免高温下反硫化反应发生，保护催化剂活性处最佳状态，寿命延长、系统阻力小、节汽、节电，具有比其他变换工艺更好地节能效果，操作方便，有效生产时间长，经济效益显著等特点。
